Thanks to Seth Rogen's name and face on the poster, "Knocked Up" was a movie boyfriends and husbands actually wanted to see with their girlfriends and wives. And they loved it as much as we did! Seth's Ben and Katherine Heigl's Alison made a couple that was both cute and sarcastic. Their relationship was just as dysfunctional as many of our own ... only much, much funnier.
